Born at Wispington, Jonathan was 23 years old when he died. He was the son of Joseph and Mary Ann Ladley. From newspaper reports, it would appear that Jonathon received a gunshot wound to his head whilst in action on the 24th March 1918. He was admitted to the 22nd General Hospital, Dannes Camiers, France where he subsequently died of his wounds on the 7th April 1918.
After enlisting at Horncastle, Jonathan found himself with the 2/4th Battalion of the Lincolnshire Regiment. This was the sister battalion to the 1/4th Lincolns, a pre-war territorial battalion, forming part of the 46th (North Midland) Division. Formed at the beginning of the war, the 2/4th served in Ireland until February 1917 when both the 2/4th and the 2/5th battalions arrived in France as part of the 177th Brigade, 59th Division. They arrived at Bayonvillers, 30 miles east of Amiens and went into the front line south of the Amiens-Estrees-Villers Carbonell road, in the first week of March.
March the 21st 1918 was the date the Germans launched their famous spring offensive. They were mindful of the fact that they needed to defeat the Allies prior to the Americans becoming involved in the fighting as their resources would be the decisive factor of the war. On the opening day of the attack we find the 4th Lincolns in reserve at Mory Camp but they were soon hastily rushed forward to the front to a position just south of Arras. It was not until the 22nd March that the battalion became involved in the fighting. As a result of some flanking German movements the Lincolns found themselves surrounded and only fierce Lewis and rifle fire enabled their withdrawal. Heavy and sustained fighting around the Arras - Bapaume area continued until the 5th April, by which time the 4th Lincolns had been releived by the 40th Division. For this period of fighting, the Regimental History of the Lincolns, records the following loses for the 4th Lincolns, one of which it is assumed was Jonathon: 6 Officers and 199 other ranks killed, wounded or missing.
